Thuringia is bordered by Bavaria, Hesse, Lower Saxony, Saxony-Anhalt, and Saxony. It has been known as "the green heart of Germany" (das grüne Herz Deutschlands) from the late 19th century due to its broad, dense forest. Most of Thuringia is in the Saale drainage basin, a left-bank tributary of the Elbe.
Basina or Basine (c. 438 – 477) was remembered as a queen of Thuringia in the middle of the fifth century, according to much later authors such as especially Gregory of Tours. However, because he described this kingdom as being on the Gaulish side of the river Rhine, it is sometimes thought to be the Civitas Tungrorum .
